A continuation is a syntactic way to define continuations of different branches of an alternative combined fragment. Continuations is intuitively similar to labels representing intermediate points in a flow of control.

Direct Superclasses: InteractionFragment

Direct Subclasses:

Class Precedence List: Continuation, InteractionFragment, NamedElement, Element

Properties:

setting : Boolean (1 1); -- source Continuation
covered : Lifeline (0 *); -- source InteractionFragment

ownedComment : Comment (0 *); -- source Element
ownedElement : Element (0 *); -- source Element
owner : Element (0 1); -- source Element

Constraints:

Signature: same_name() : Boolean;
Description: Continuations with the same name may only cover the same set of Lifelines (within one Classifier).
Expression: true

Signature: global() : Boolean;
Description: Continuations are always global in the enclosing InteractionFragment e.g. it always covers all Lifelines covered by the enclosing InteractionFragment.
Expression: true

Signature: first_or_last_interaction_fragment() : Boolean;
Description: Continuations always occur as the very first InteractionFragment or the very last InteractionFragment of the enclosing InteractionFragment.
Expression: true
